物件導向的 Python
Python 是一個物件導向（object-oriented，OO）程式語言。跟某些其他的
物件導向語言不同，Python 並不會強迫你只能使用物件導向典範：它也
以模組（modules）和函式（functions）支援程序式程式設計（procedural
programming），所以你能夠為你程式的各個部分選擇最佳的典範
（paradigm）。物件導向典範能幫助你將狀態（資料）和行為（程式碼）包
成一組便利的功能性。當你想要使用涵蓋於本章中的某些 Python 物件導向
機制，例如
繼承
（
inheritance
）或
特殊方法
（
special methods
），它也能派
上用場。如果你不需要物件導向程式設計的功能，那麼基於模組和函式的
程序式典範，可能會更為簡單且合適。透過 Python，你能夠混合搭配這些
典範。
今日的 Python 具有跟多年前不同的物件模型（object model）。本章只會描
述所謂的
新式模型
（
new-style
）或
新物件模型
（
new object model
），它較
為簡單、更規則、更強大，而且也是我們建議你
永遠
都選用的那一個。每
當我們談及類別（classes）或實體（instances），我們指的都是新式的類別
或實體。然而，為了回溯相容性（backward compatibility）， v2 中預設的
物件模型是
傳統物件模型
（
legacy object model
），也叫做
古典
（
classic
）
或
舊式
（
old-style
）物件模型，而 ...
